It's not about giving Nazr a fair shake, and it's not about Malik. It's about this team being put in the best position to win a championship. Nazr on this team at this point in time is not nearly as usefull as Malik would have been, and that's a given. Malik may not have contributed exactly what we needed, but the mere fact he would have contributed at all is what seperates him from Nazr.
Look, I know hindsight is 20/20 and I too thought this trade could be good basketball wise at the time of the trade. Nobody knew Duncan was going to go down. That's all fine, but the trade still sucks for this season.
Nazr still has a chance to be a damn good player in this system, but it is not going to be this year. Comparing him to Barry is flawed because one was an off season acquisition and one was a late season one. Barry had time to learn the system, and has ultimately come around. Nazr simply doens't have that luxury this year, and has done nothing to give an indication that he will be able to provide anything in a positive manner before the season is over.
Marks knows the system. Mass knows the system. Both have played well in spots, which is more than you can say for Nazr. At this point, I'd easily rather have both of them on the roster. I think even with minimum improvement Nazr can secure his spot on the post season roster, but as I said before, he has given absolutely no indication that he can even improve a little. In fact, the first thing he needs to stop is his regression, he gets worse each game.
